Happy St. Piglet's – er, St. Patrick's – Day!

This little piggy pushing his cart o' Guinness is guaranteed to get you in the Irish spirit.

The petite porker may look jovial, but photographer Richard Austin told TODAY.com that the "micro pigs," bred at Pennywell Farm in Devon, England, actually can be a handful to photograph.

"Some piglets are too boisterous to photograph," he explained. "Some are subject to temper tantrums just like small children ... if they do not want to be photographed, forget it, choose another pig because they all have different temperaments."
